Observations performed across the electromagnetic spectrum from radio to X-rays in the last decade have established the widespread presence of powerful winds involving all gas phases and all spatial scales, from the parsec sizes to thousands of parsecs. The detailed study of these winds is one of the most growing and dynamic areas of present-day astronomy and is ubiquitously present in the core science programs of recently-delivered and future astronomical facilities. How galaxy-scale winds originate and how much energy they carry and deposit into the ISM is a major issue for current research in extragalactic astrophysics.

A combined theoretical and observational effort has been recently devoted to understand the acceleration mechanism(s), physical properties and fate of AGN and starburst winds, given their important implications for the evolution of galaxies. The timing of this Symposium is especially propitious to address the following key questions:

• How many wind flavors are there?
• How do galaxy-wide winds accelerate and expand?
• How kinetic power and mass-loading factor for the wind can be accurately derived?
• What is the fate of AGN outflows and superwinds?
• What is the role of AGN outflows and superwinds in the evolution of the host galaxy ISM, and in the stimulation or suppression of star formation?
